FASTENER.

SELECIFICATION forming part of Letters Patent No. 667,874, datedFebruary 12, 1901. Application led May 5, 1900. Serial No. 15,641. (NomocleL To f/,Z whom z'f may concern:

Be it known that l, ALBERT F. FISHER, a citizen of the United States,residingat Dedham, in the county of Norfolk and State of Massachusetts,have invented new and useful Improvements in Fasteners, of which thefollowing is a specification.

'lhe object of this invention is to produce a strong, convenient, anddurable snap-fastener for boots and shoes, gloves, and clothing and toproduce a fastener which shall not become accidentally unfastened by thepressure or strain brought to bear thereon (tending to unf-asten thesame) by the hand where the fastener is applied to a glove or the footwhen said fastener is applied to a D001).

The invention consists of afastener in two parts, a sind and a cap, saidstud consisting of a plate having' a bifnrcated standard thereon adaptedto engage a rib extending diagonally across the interior of a hollowhemispherical cap.

The invention further consists in means whereby said cap is preventedfrom moving upon said stud lengthwise of said rib.

The invention still further consists of the combination and arrangementof parts set Vforth in the following specification, and particularlypointed out in the claims thereof.

Referring to the drawings, Figure 1 is an enlarged side elevation,partly in section, of my improved fastener, showing the same applied toa portion of the upper of a boot or shoe, said upper being shown insection. Fig. 2 is a sectional elevation of the same, taken on line 22,`Fig. 1, looking toward the left in said figure. Fig. 3 is a sectionalelevation similar to Fig. 2, showing the cap in section and the stud inelevation. Fig. L1 is a perspective view of the fastener-cap shown inFigs. 1, 2, and 3, having ears by which said rap is attached to thematerial in lieu of the flange shown on the cap in said figures. Fig. 5is a perspective view of the fastener-stud. Fig. o' is a plan View ofthe fastener-cap. Fig. 7 is a perspective view of a portion of the upper of a boot or shoe with my improved fasteners attached thereto.

Like numerals refer to like parts throughout the several views of thedrawings.

In the drawings, l0 is the fastener-cap, and

11 the fastener-stud. Said fastener-stud consists of a flat plate 12,having prongs 13, by which said stud is fastened to the stock 14 of theupper of a boot or shoe.

15 15 are two standards formed upon the plate l2, each consisting of ashank portion 16 and a curved rounded head portion 17. Each of the shankportions lo is provided with a notch 13 to engage a projection upon thefastener-cap, as hereinafter described.

The fastener-cap 10 is formed, preferably, of sheet metal, and consistsof a hollow hemisphere having a flange 10 thereon, as shown in Figs. 1,2, and 3, or ears 20, as shown in Figs. 4 and 6, said flange or earsbeing perforated to enable said cap to be attached to the stock 14 bythread 21. The fastener-cap has a depressed central portion or rib 22,which extends diagonally across said cap and is rounded out at the lowerportion thereof to engage the standards 15 15. A projection 23, formedupon the cap l0, engages the notches 18 upon the standards 15.

The operation of the device is as follows: The fastener-cap is presseddown upon the stud 11, the depressed or rib portion of said cap enteringthe space 24 between the standards 15. Said standards spring apart andallow the enlarged lower portion 25 of the fastenercap to pass betweensaid standards and to enter the enlarged port-ion of the space 24Ebetween said standards, whereupon the stand ards spring back to theirnormal position and prevent the cap from moving upwardly. When the caphas been pressed upon the stud, hereinbefore described, the projection23 enters the notches 1Sin the standards 15 and the rounded headportions ofrsaid standards abut against the inner face of theheinispherical cap. When the cap is pressed onto the stud, as shown inFigs. 1, 2, and 3, said cap is prevented from becoming accidentallydetached therefrom by any movement or strain brought to bear thereon bythe foot inclosed in the shoe, by the springstandards which incl'ose therib 22, and by the projection 23, .which is engaged by the notches 1S.It is evident that the cap cannot move lengthwise of the rib 22, as itis prevented from moving to the right, Fig. l, by said projection 23,which bears against the standards 15, and from moving to the left in IOOsaid figure by the heads 17 of said standards, which bear against theinner face of the cap.

The only manner in which the cap can be detached from the stud is bylifting up the stock attached to the cap at the right-hand side of saidcap, Fig. 1, until said cap has been raised to a sufficient extent toallow the projection 23 to be disengaged from the notches 1S, when thestandards 15, spread-ing apart, allow the rib 22 to pass out frombetween them, and the cap will then become disengaged from the stud.

It is evident that the cap may be made from a solid piece of metal andthe outer surface thereof be perfectly smooth with no depressiontherein, the rib 22 being formed solid thereon or fastened thereto,without departing from the spirit of my invention. It is also evidentthat the two standards 15 15 are of said cap and adapted to engage eachof said standards; and notches in said standards arranged to engage aprojection upon said cap.

2. In a fastener, ahollow hemispherical fastener-cap, a rib extendingdiagonally across said cap; in combination with a pair of standards upona fastener-stud, said standards being integral with a plate and having ashank portion and an enlarged head portion, said rib arranged to engagesaid standards; and

r a projection upon the interior of said fastener-cap arranged to engagenotches in said standards.

3. A fastener in two parts; a stud consisting of a plate and twostandards integral therewith, each of said standards having a shankportion and an enlarged head portion; and a hollow ltemispherical cap, arib extending diagonally across said cap and ar- .ranged toengage saidstandards; notches in said standards and a projection upon said caparranged to engage said notches.

1n testimony whereofl I have hereunto set my hand in presence of twosubscribing wit messes.
